'The Crimes of Alexander Borgia' is a fictional caricature of Pope Alexander VI (Alexander Borgia) by an anonymous author, probably of American origin. A young woman Donna Lucretta shows up at the Papal residence claiming to be the pope's daughter and threatening to reveal his secrets to all. But she seems to have underestimated the unscrupulous nature of Borgia, who threatens her with the execution of her lover, Mercardo. The interesting claim of the author is that the stories mirror actual history.
